How is that KISS? Are you saying they hacked into Hillary's server, read emails with names of agents, and rounded them up? That's not KISS and there's no evidence for names like that being in any of the emails.
Here's KISS: some crappy CIA software connected clients back to a "secret" proxy somewhere. The Chinese figured out that the proxy belonged to the CIA, which can be leaked (KISS) or figured out (not quite as simple but doable). Then anybody connecting to that proxy would be rounded up. Sometimes that would require arresting everyone at the internet cafe and going through all of the computers, but that's easy for Chinese Communists..
IIRC Holder, Comey, Rice, Brennan(?) and a bunch of other top officials had private servers or used public email for government business, to get around federal documentation regulations of email traffic. That were put in place by the Dems themselves.
This article goes all the way around the bend to try to keep from mentioning the multiple security violations that were ignored under the Obama regime.
So they blame the Chicoms, or the faceless coders. Anything to keep from implicating the men in the high towers.
